Fix Macaroni and Cheese according to box, except melt the butter in the pan, mix in the cheese, then mix in the milk, stir until smooth, then add the noodles and mix thoroughly. This will make creamier M&C and the cheese will be more evenly spread. While making M&C, brown hamburger in skillet and heat chili in saucepan. When all ingredients are prepared, mix the Hamburger and Chili into the M&C. Serve Hot. You can create variations of this using hotdogs or hot sausage instead of hamburger (I like Hot Sausages and Hot/Spicy Chili) and introducing other ingredients such as Olives or Onions.
